Limitations of Statistics
Statistics is an important tool used to collect, analyze, and interpret numerical data in economics, business, and education. However, statistics has certain limitations that restrict its accuracy and applicability. It deals only with quantitative data, studies aggregates rather than individual cases, and produces results that are true only on average. Statistical conclusions depend heavily on data quality, methods used, and correct interpretation.

Why Are Resources Distributed Unequally Over the Earth?
Resources are distributed unequally over the earth because natural conditions are not the same everywhere. Factors such as geological structure, climate, landforms, and natural processes determine where resources are found. Minerals develop over millions of years in specific rock formations. Water and forests depend on rainfall and temperature. Fertile soil is mainly found in river plains, while deserts and mountains have limited resources. Since these physical conditions vary from region to region, resources are unevenly distributed across the earth.
